Title:

HALOGEN-FREE FLAME-RETARDANT SEMI-AROMATIC POLYAMIDE COMPOSITE MATERIAL, PREPARATION METHOD THEREFOR, AND USE THEREOF

Document Type and Number:

WIPO Patent Application WO/2024/066970

Kind Code:

A1

Abstract:

Provided are a halogen-free flame-retardant semi-aromatic polyamide composite material, a preparation method therefor, and use thereof, which belong to the technical field of polymer material modification. The halogen-free flame-retardant semi-aromatic polyamide composite material comprises the following components in parts by weight: 35-50 parts of a semi-aromatic polyamide resin, 10-22 parts of a dialkyl hypophosphite flame retardant, 15-50 parts of a reinforcing material, and 0.2-2 parts of a carbonic acid compound. The semi-aromatic polyamide resin comprises any one of PA10T, PA10T/106, PA9T and PA12T. The amine-carboxyl ratio of the semi-aromatic polyamide resin is 1.02-1.08. The mass ratio of the carbonic acid compound to the dialkyl hypophosphite flame retardant is 1:(9-90). With no impact on foamability and its mechanical properties, the product provided also features low corrosivity, V-0 halogen-free flame retardance, and resistance to yellowing, and meets SMT process requirements. In addition, the added carbonic acid compound is inexpensive and easily available, and the preparation method is simple, and facilitates actual production.
